RAFAEL PADILLA, or HABANA, CUBA.

ADVERTISING DEVICE.

Application filed August 31, 1917.

To all whom t may concern:

Be it known that I, RAFAEL PADILLA, a citizen of the Republic of Mexico,residing at Habana, in the Province of I-Iabana, Cuba, have invented newand useful Improvements in Advertising Devices, of which the followingis a specification.

This invention relates to improvements in advertising andnews-disseminating devices.

The principal object of the invention is to provide a device of theclass described having a transparent face which is divided in sections,each corresponding to a different class of advertisements or news, andbehind which is mounted for movement an elongated strip of llexiblematerial adapted for carrying strips of paper upon which are inscribedthe news items or advertisements so that the latter will successivelybecome visible through the proper divisions of the face in the movementof the strip.

Another object is to provide rolls for carrying the strip so that thespace occupied by the mechanism will be limited to the greatest possibleextent.

A further object is to provide means for automatically reversing therolls to reverse the direction of travel of the 'strip each time it iscompletely unwound from one of the rolls. In addition it is proposed toprovide a flexible strip which is coated with adhesive material andthereby adapted to retain the strips of paper or other material uponwhich the advertisements or news items are inscribed, so that the lattermay be conveniently applied while the flexible strip is in motion, andmay be readily removed when desired.

The invention further contemplates an improved arrangement of thevarious parts of the device whereby it is rendered more convenient andelicient in operation. One form of the invention isy described in thespeciication below and illustrated in the accompanying drawings, and thenovel features of the invention are more broadly set forth in the apended claims.

In t e drawings Figure l represents a front elevation ofthe preferredform of the invention.

Fig. 2 is a side elevation of the preferred form of the invention,showing the housing partly broken away to expose the interior.

Fig. 3 represents a transverse section through one of the rolls and theattached flexible strip for carrying the news items.

Specicaton of Letters Patent.

Patented Aug. 12, 1919.

Serial No. 189,195.

Fig. 4 is an end view showing in detail a pair of rolls and associatedparts, including the motor reversingmechanism, and showsdiagrannnatically the various circuits involved.

Fig. 5 is a fragmentary side elevation of a pair of rolls and associatedparts and shows the arrangement of the ilexible strip in greater detail.

In the drawings the numeral l indicates the `device as a whole. It has asuitable housing or casing 2 for containing the mechanism. Preferablythe housing 2 is of sulicient size yand so arranged as to form aconvenient shelter for the operator of the device. In the presentinstance it has the form of a kiosk or booth which may be located in anypublic place where it will readily attract attention. One side of thehousing 2 has a suitable opening or window 3 through which the operatormay conveniently receive advertisements or other matter to be displayedby the device, or carry on any other necessary transaction. A section 4of the wall of the housing is composed of transparent material,preferably glass. The section 4 is divided in any convenient manner intoa plurality ofv sections 5, eachcorrespending to a particular class ofnews items or advertisements, and each headed with a correspondinginscription. Behind the transparent section 4 are mounted a plurality ofrolls 6 arranged in pairs extending preferably4 horizontally inproximity and parallel to the section 4. Mountings are provided for therolls 6 by which they are adapted for rotation. In the present instancesuch mountings consist of vertical frame members 7 carrying transversemembers 8 in which the shafts 9 of the rolls are suitably j ournaled.Each roll 6 has attached thereto one end of a flexible strip 10 whichmay consist of cloth or any other suitable material. In the presentinstance the strips l0 are attached to the rolls 6 by suitable elongatedclamping members 11 adapted to be clampingly engaged against the rolls 6to hold the strips l0 by means shown as screws 12. The strips l0 are ofsuch length that when one of the rolls 6 is Ifilled to the limit of itscapacity, the respective strip will be completely unwound from the otherroll 6. Each strip is adapted to travel behind a respective member ofthe sections 5 in its movement, so las to cause to be successivelyexposed to view through the sections 5 the news items, ad-

vertisements or similar matter, preferably inscribed on suitable stripsof paper and attached to the flexible strip 10. In order to render suchattachment convenient while the strip is in motion, I prefer to coat thelatter on the side which is adapted to become visible through the face4, with a layer of adhesive material. By this means it will be seen that'any desired strips of paper may be instantly' applied and as theadhesive material is of sucli a character as not to dry or hardenquickly the strips of paper may be readily removed`w-hen desired; Inorder to prevent yadjacent layers of the flexible strip or web 10 fromadhering when wound upon the roll 6 I' may provide narrow flexiblestrips 24, as for instance of felt, which eX- tend longitudinally of thestrip 10 and are suitably attached to the latter on the reverse side.Preferably the strips 24 coincide in position with the` divisionsbetween the sections 5, and the Iadhesive material is applied only tothose portions of the strip 10 between the strips 24.

For rotating the rolls 6 a` suitable mechanism is provided which will beautomatically operated to reverse the direction of rotation each timethe flexible strip 10 is completely unwound from one of the rolls 6 ofthe respective pair. In the preferred form shown this is accomplished byproviding each roll shaft 9with an extension carrying a beveled gear 11"engaging with a beveled gear 12on a vertical shaft 13 which is properlyjournaled in convenient bearings 14 which may be attached to the framestructure of the device. A motor, preferablyan electric motor, andindicated in the drawing by the numeral 15, isconnected to one end ofthe shaft 13, suitable gearing being interposed when necessary to reducethe speed'of the rolls to a desired degree.

In order to cause the motor 15 to be automatically reversedat a properpointin the movement of the strips, the rolls 6 andv the frame members 8in which they are journaled are' in the present instance of metal. Eachframe member 8 of those provided for a particular pair of the rolls hasan extension 16. Mounted upon but insulated from the extensions 16 arespring contact arms 22 adapted to bear at one end against the strip offlexible material wound upon the particular roll, and so arranged thatwhen the strip of material is completely unwound the end of the contactarm, which may be provided with a roller 17 to reduce friction, willestablish electric. connection with the roll. A reversing switch 18 isproperly connected to the motor 15 andto the source of current supplyand carries lan armature 19` disposed for attraction by a pair ofmagnets 20. The

magnets 20 are arranged on opposite sides of the armature 19 so thatwhen one of the magnets is energized 1ty will actuate the switch 18 tocause the motor 15 to rotate in one direction, while when the othermagnet is energized it will actuate the switch to cause the'motor torotate in the other direction. Each magnet 2O has one terminal connectedto a suitable battery 21 or other source of current supply, and theremaining terminal of each is connected to the respective contact arm22. The circuit is through a given magnet, arm 22 connected therewith,roller 17, large roll 6, and frame 8, which is in electrical connectionwith one terminal of the battery; the circuit being completed throughthe other terminal of the battery and that magnet having connection withan active contact arm 22.

A suitable switch 23 is inserted in the motor circuit to permit thelatter to be interrupted to stop the motor when desired; In order toenable the device to be effectively used after dark, electric lamps 24are properly disposed in proximity to the transparent face 4 of thedevice.

From the above description taken in connectionv with the drawings itwill be seen that in operation the strip 10 will be actuated by therotation of the rolls 6 to which it is connected to travel backward andforward behindthe respective divisions 5, and that the operator withinthe kiosk or booth may conveniently apply to the flexible strip at theproper points in its movements, the strips of paper bearing theadvertisements and similar matter which it is desired to expose topublic view, andr may with equal 100 convenience remove the latter whendesired. It will be understood that the operator may be vprovided withthe necessary telephonic or other instruments for communicating with acentral news agency.

. The above described. embodiment of the invention, while constituting apreferred form, represents only one of many embodiments comprised withinthe spirit and scope of the invention and the right is reserved tovariations and departures therefrom falling within the latitude of theinvention as defined by the claims.

What is claimed is 1; In a device of the classdescribed, a 115 pluralityof rolls, a web to be wound thereon, strips carried bythe web, thestrips providing spaces therebetween for advertising matter to becarried by the web, and means for controlling the movement of the rolls,said means including elements bearing against the strips during themajor portion of each revolution of the rolls.
